Need to reset to factory settings: my Lenovo Thinkpad is locked because I cannot find my password and I don't remember my log in. Can you tell me how to reset it to factory settings?
If you are talking about the BIOS password right after you boot the Laptop you have four ways.
It is a special security feature of Thinkpads that you cannot simply short a jumper and reset the BIOS by doing so. Source: ThinkPad on German Wikipedia.
